[PATCH] drm/bridge: nxp-ptn3460: Remove a small useless code snippet

[Sui Jingfeng <sui.jingfeng@linux.dev>]

In ptn3460_bridge_attach(), the check on the existence of bridge->encoder
has already been done in the implementation of drm_bridge_attach(). The
driver won't go further if bridge->encoder is NULL and the driver will quit
even if drm_bridge_attach() fails for some reasons. Thereforei, there is
no need to check another time at the later, remove the redundant checking
codes "if (!bridge->encoder) { ... }".
